Hi,
the linux server is has MB7 and MQ7 in which a queue has input count as 2. So with a queue status I get to know the process ids (both are same) and from which I get to know there are DataFlowEngine (msg flows).
So now how can I know which flows are listening to the queue.
(this is a kinda reverse engineering concept to know the flow names that are listening to the queue)
Pls suggest the methods other than checking all the flows ( in UI, broker toolkit) to know which flow is having the input queue as the expected queue as there are hell a lot of flows.
Thanks, |

Well, sorry, but you are going about this backwards.
You shouldn't deploy anything without knowing before hand what queue it will listen to.
If you really somehow don't know this, and don't want to bother doing things like reviewing the properties of the flow on the administrative view (rather than actually looking at the .msgflow file!), then you can enable user trace on the EG and send a message to a queue. Then look at the user trace to see what flow read the message.
But again, this is the wrong way to do it. You should know before hand what queues will be used, or enforce what queues will be used by overriding the bar file. |

It complains by writing a message into the log.

The logged messages will mention the queue Name and give an MQRC = 2016.
simples. Try it and see for yourself.

| I think you *might* be able to get this info back using the CMP API. Im on my home PC so dont have a broker to check. Its worth having a poke around in the CMP exerciser to see if you can find the deployed flow cmf. |
